[Premium-Rx] Frequency Divider Question

[Keith Densmore]

Greetings Listmates,

I am somewhat irritated by the warm up drift of my military Harris 590A, 
(R-2368) while the crystal oven comes up to temperature.
As a non-invasive solution I would like to use an external rubidium 
frequency standard, but, the one I have here is 10 MHZ, and the Harris input 
is 1 Meg.
Question...does anyone know of a (cheap and/or easy) programmable frequency 
divider that could do the job? (or a fixed 10:1 divider would do too). 
Suggestions welcomed.
